So, as I said, you need to tell the client to use passive mode. If your client can't do passive mode, then you'll need to get a better client. You can't get the client into passive mode by manually sending "quote" a PASV command to the server. My XP ftp has no problems with it. Wim Wim. Is it doing passive transfers? How do you know? But that has no effect on any future file transfers. And if it has a "debug" mode.
You'd have to use some other FTP client e. Steven, I used "quote pasv". I do not know how ftp is reacting if a firewall is filtering out the PASV command hey, it's just a program. It could be that it reacts with "unknown command" or something like that.
That's why I propose a tcp trace. As long as we don't have the exact error messages, everything is open. BTW I did get an Active FTP is the protocol that requires the the server to open a connection to the client on a port that the client specified. Is there some setting that needs to be made in order to have Windows Firewall automatically detect Active FTP and open up the necessary ports as needed? Can I change that setting programmatically? Here's the thing: Whether in Active or Passive mode, the server always uses port 20 on it's side for the data connection and connects to the client on whatever port the client specified when it issued the FTP PORT command.
After looking at the Windows 7 firewall it looks like you can create a custom inbound rule that allows connections to any local port from a specific remote port 20 for a given protocol type TCP.
You can also specify the local and remote ip addresses that this rule applies to. I have to admit that I've never monkeyed around with the Windows firewall but it looks to me like it might work for you. Instead of adding ports to the Windows Firewall exception list, add the application you need to have access. Windows Firewall will then allow that application to bind and use whatever ports it wishes.
You need to ensure that this service is started for Active FTP to work. I had the problem with an FTP client on our Intranet, and didn't want to make a firewall exception for that particular program.
I tried to enable the "Application Layer Gateway Service" sc start ALG , and made sure that I had "statefulftp" enabled netsh advfirewall set global statefulftp enable. I suppose these are needed in some cases, but they didn't make a difference for me.
I resolved this issue looking more accurately at the top of inbound rules. Disabled both and everything worked like a charm! Just my 2 cent ;-. The application must be white listed before you access the connection from your sub-net or the internet.
Then add exception for "inetinfo. I would recommend tunneling instead. It has UPnP and will auto open the port 22 for you. It has an accompanying client program called Tunnelier if you coming from the client side. The point here is that when you have a tunnel on port 22, then both active or passive FTP will work fine from that point forward via the tunnel.

This can be beneficial to other community members reading the thread. Monday, November 7, AM. The same thing is happening on my W7. It used to be fine and the behaviour just changed recently. Entering ftp. Now it redirects to my default browser Firefox. I've no idea what has triggered this new behaviour, but I'd really like to be able to open ftp sites in WE again. Monday, November 28, PM. On the Tools menu, click Internet Options.
Click the Advanced tab. Click OK. I have reset my IE settings. I have restored the advanced settings. Doesn't matter if either one or both are unchecked. Same problem here - Windows 7 bit Ultimate!
